Answer:

15.4%

Step-by-step explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

$V_{A}$ = π × 10² × 11 = 1100π ft³

$V_{B}$ = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

$\frac{left}{full}$ × 100%

= $\frac{169\pi }{1100\pi }$ × 100%

= $\frac{169}{1100}$ × 100%

= 15.4% ( to the nearest tenth )

Write an equation for a quadratic function in factored form with

Fittoniya [83]

Answer:

$f(x)=-2x(x+4)$

Step-by-step explanation:

We want to find the equation of a quadratic function in factored form with zeros at x = -4 and x = 0 that passes through the point (-3, 6).

The factored form of a quadratic is given by:

$f(x)=a(x-p)(x-q)$

Where p and q are the zeros and a is the leading coefficient.

Since we have zeros at x = -4 and x = 0, let p = -4 and q = 0. Substitute:

$f(x)=a(x-(-4))(x-0)$

Simplify:

$f(x)=ax(x+4)$

And since we know that the function passes through the point (-3, 6), f(x) = 6 when x = -3. Thus:

$(6)=a(-3)(-3+4)$

Simplify:

$6=a(-3)(1)$

Thus:

$-3a=6\Rightarrow a=-2$

So, our quadratic function is:

$f(x)=-2x(x+4)$

Ther are 10 girls and 8 boys in Mr. Augello's class. If 5 more girls and 5 more boys join the class, will the ratio of girls to

NISA [10]

Presently ratio is at 10:18 = 1.25
With 5 more girls & guys joining, ratio would change to 15:13 = 1.153846154
Therefore, the ratio of girls to boys would change rather not remain the same.
